4 claims. (cl. 124-35) i This invention relates to improvements ingripping and triggering devices adapted to be for use by archers.

A major object of the invention is to provide an improved andsimpliedarchers hand grip and trigger device which reduces the skill heretoforerequired for proper gripping ofthe bow string with a conventional arrowin nocked engagement therewith, while simplifying manual release of thearrow from a desired anchor point, such as from a chin anchor or a cheekanchor, substantially to improve the marksmanship of the average archer.

A further object is to provide an improved archers hand grip and triggerdevice which permits archers of limited skill to use the same arm andhand movements employed by highly-skilled archers without use of thegrip, and to do so in the absence of the substantial skill heretoforerequired for perfect linger release of the bow string, thus reducing thetime heretofore required to obtain archery proficiency. v Other objectswill be in part obvious, and in part 'pointed out more in detailhereinafter.

f The invention accordingly consists in the features of onstruction,combination of elements and arrangement .Joffparts which will beexemplified in the construction hereafter set forth and the scope of theapplication of which will be indicated in the appended claims.

`In the drawings: v

lFig. l is a side elevation, partially in phantom of a hand gripmechanism incorporating the invention.

Fig 2 shows in elevation a hand grip mechanism havgan alternateembodiment of the invention incorporated therein.

Fig. 3 is a vertical section of the-shank portion of the device of Fig.2.

Fig. 4 is a top plan view of the device of Fig. 1.

Fig. 5 is a section taken along lines 5--5 of Fig. 1 with the jaws ofthe device closed.

Fig. 6 is a view similar to Fig. 5 but with the jaws open.

Figs. 1, 4, 5 and 6 show an 'archers triggerable hand j grip deviceincorporating a preferred embodiment of the invention and comprising ashank-like finger grp'10 and forwardly extending set of ljawsgenerically designated 11. Jaws 11 include a jaw arm 12 having one endfixed to shank 10 as by welding, the drawings showing that arm as anintergral extension of the shank material for convenience ofillustration. A second jaw arm 13 is mounted to pivot in respect to arm12, as later described, both arms 12 and 13 being of identicalconfiguration forwardly of the pivot point of arm 13 to terminate inenlarged jaws 16 and 17, contoured to define, when closed, an ontwardlyopen cylindrical arrow nock receiving socket 18 positionedlongitudinally of the arms and a vertical string bore 19 `disposed tointersect socket 18. Jaws 11, when open, receive arrow 61 with bowstring60 nocked thereto, and when closed, lock the arrow and string therein.

Shank 10 preferably is diagonally positioned in respect to arms 12, 13to facilitate ease of hand positioning at spaced plates 23, 24 which aremounted to the top and bottom surfaces, respectively, of arm 12' byrivets 25 and extend laterally of arm 12 a sufficient distance to anchorpintle 22 as shown. Shank 10 is provided with a centerbore 28 extendingdownwardly to terminate in a closed end 29, the upper end thereofleading into a diametric channel 34 between shoulders 30 and 31,extending downwardly to shoulders 33 and 41. A closure member 36 ofright angular shape is disposed in channel 34 and riveted to shank 10 at37 with one'leg 35 thereof closing the upper channel end and the otherleg 40 closingthe side above arm 12, leaving the opposite side ofthe-channel open fromthe lower face of leg 35 to the bottom shoulder 33thereof.

Referring to Figs. 5 and 6, the inner end portion 17 of leg 13 istapered, starting near pintle 22, to reduce the leg to approximatelyhalf its width at the inner Vend thereof, thus permitting pivoting ofthe outer end of leg 13 to the jaw open position of Fig. 6 whichpositions the inner tapered end thereof in abutment with the innersurface of arm 12 as shown with tongue 14 extending into the shank bore.To provide clearance for such pivoting, shank 10 is provided with aforwardly opening notch 43 is disposed within centerbore 28, the upperend thereof carrying a thumb depressible lever 53 projecting throughslot34 for movement of plunger 45 downwardly against the bias of a coilspring 46 in bore 28, the limits of movement of plunger 45 being set bystops 33 and 35 respectively. Plunger 45 is provided with a forwardlateral notch 49 shown dotted and above shank notch 43, Fig. l, butregisterable, with the plunger depressed, with shank notch 43 to permittongue 14 of arm 13 to be swung into bore 28 to be detent held therein,upon plunger release. Upon manual closure of jaws 11, tongue 14 swingsout of bore 28 and plunger 45 snapsuupwardly to prevent tongue 14 frommoving inwardly, thus locking the jaws until released by subsequentdepression of plunger 45. With a drawn bowstring held in the stringbore, the jaws instantly fly apart upon depression of plunger 45 bylever 53 with attendant release of the arrow.

In the device of Figs. 2 and 3, shank 110 is shown disposed in rightangularity to the jaw members 111 rather than being diagonally disposedin respect thereto. The device functions in a similar manner, however,with plunger provided with a forward notch 65 for registry, whendepressed against spring 146 by thumb engageable extension 70 with shankgroove 143 to permit tongue 114 of pivoted arm 113 to enter notch 65,thus opening the jaws, tongue 114 being detent held by plunger 145 underurge of spring 146. When the jaws are closed, plunger 145 snaps upwardlyto lock them in the manner above described. Plunger 145 is provided withan axially extending notch 66 into which the inner end of a stop member67 projects to limit the vertical movement of plunger 145.

' I claim:

1. In a device of the character described, a first jaw having acenter-boredv handle secured thereto in a plane transverse to the axisof said jaw and having handle portions disposed above and below saidfirst jaw, a second jaw pivotally attached to said first jaw formovement yabout an axis generally co-planar with said handle andPatented May 17, 196)` biasing spring, to provide clearance permittingsaid tongue portion to be swung into the centerbore.

2. -In a device of the character described, a shank, a pair of arrownock and bowstring recreiving'jaws extending laterally from said shankintermediate the ends thereof, one jaw being fixed thereto and the otherjaw pivotally attached to the xed jaw for movement about an axisgenerally co-planar withl said shank, said shank being longitudinallychambered and radially notched adjacent the base of the jaw fixedthereto, said pivoted jaw including a tongue positioned to be pivotedinto said shank notch, a plunger in said chamber provided With a notchto allow pivoting of said tongue into said chamber when aligned with theshank notch and to prevent such pivoting when non-aligned therewith, adepressible lever extending outwardly of said shank for the control ofsaid plunger, and a spring biasing said plunger in a position ofnon-alignment of said notches.

3.
